Harry's visit during April 2019 was hosted by Professor Wu Kaiming, and involved research discussions and a lecture on difficulties in the theory of diffusion-controlled growth. Wuhan is one of the fastest progressing cities in China, a hub for technology. It has the largest population in the world, of University students, at 1.3 million, for a total city-population of 10 million.
